Women with a history of any chronic illness, hormone replacement therapy, smoking, alcohol use, medication use and surgical removal of the uterus or ovaries were excluded. Their age, body mass index, and blood pressure were recorded. Data on the complete history of VMS, clinical history, medications, menstrual history, and exercise habits were collected using a self-reported questionnaire. Cardiac autonomic function was evaluated using heart rate variability (HRV), heart rate response to standing and deep breathing, and Valsalva ratio. Data were analyzed using SPSS 21 IBM software, and correlation and regression analyses were applied for statistical evaluation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      The participants\u2019 average age was 43.31 \u00b1 4.10 years. VMS included mood swings, night sweats, sleep disturbances, and hot flashes.
